Here is what you want: Low thrust long burn, won't shred balsa fins as long as you use some decent fillets. Carefully remove the glassine layer where the fins will attach, about 1/16" wider than the fin root thickness.

Bonus: lower speed means lower dynamic drag and should produce higher altitudes. Thrust curve says the E6 burns for 5.8 seconds. The closest to that is the Estes E9 at 3.1 seconds.
To the OP
I would add that epoxy is not stronger than wood glue when joining wood to paper (it's also heavier). You want some weight though for inertia (difference between throwing a baseball vs a wiffle ball sort of thing) but you want that up front not aft for balance too. Keep running sims and find that optimum weight.
